Just got it half an hour ago. Pretty late but all good in the end.I did the same as you for this match, sold my season ticket seat and bought a different seat on the exchange. I bought the new ticket on Thursday afternoon and got an email with a new e-ticket to add to my phone on Friday morning, so you should definitely have had something. I'd check your spam folder in case it went into there, and definitely give them a ring if there's nothing in there.
